SAFETY DOOR FOR SAFES.

Application led March 6, 1926. Serial No. 92,824.

so as to render the safe or vaults to which same is attached burglar proof.

Another object ot' the invention is to provide a safe door oi' n-ovel construction and arrangement ci' parts.

For further comprehension of the invention, and of the objects and advantages thereof, `reference will be had to the follow ing description and accompanying drawing', and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing, shows a perspective view of a safe with my improved sate door attached thereto.

Fig. 2 shows an enlarged view partly in section of certain parts of the operating mechanism as used in connection with my improved device.

Fig. 3 shows an enlarged perspective view of other parts of the operating mechanism as used in connection with my improved device.

The safe, vault, or safety deposit box, designated by the reference number 10, has a door 11, andis imbedded in the wall 12, of a building, having a floor 13. The above mentioned articles and elements are of comlmon design and construction, such as ordinarily used.

As here embodied my improved device comprises a supplementary safe door 14,y of suitable dimensions to encloseor cover the front of the safe 10. The supplementary safe door 14 is slidably located in the verti- Cal guides 15 and 16, one of the said vertical guides extends to the bottom of the safe 10, as at 17, and has a rack 18 formed therein or attached thereto, suitably located to mesh with the gear 19, which is rotatively mounted on a shaft 20, rigidly attached to the supplementary safe door 14, the operating handle, or crank 21, is rigidly attached to the gear 19, the above mentioned construction being such as will permit the supplementary safe door 14 to be raised or ex-` tended above the safe door 11, as clearly shown in Fig. 1, of the accompanying drawing.

lt will be understood that the here#y tobefore mentioned guide 16 does not extend past the safe door 11, but that the supplementary saie door4 14 is of suitable height to engage the lower portion of the guide 16, when the supplementary safe door is in a lowered or closed position. Y

The catch 22 is pivotally attached to the back of the supplementary door 14, as at 23, and has an offset extremity 22 provided with a notch 24.

The catch lever 25, is pivotably attached to the wall 12, as at 26, preferably at or near its center, and has an upper offset portion 27 provided with a pointed extremit 28, to engage the notch 24 of the catch 22. The horizontal bar 29 is slidably located in the support 30, which is rigidlyattached to the wall l2, as at'31, and is suitably located and has ayoke 32 at one extremity which is pivotally attached to the .elongated aperture 33 located in the lower extremity of the catch lever 25, by means oi' the pin 34, rigidly attached to the yoke 32 and e2'- tended through the elongated aperture 33. The horizontal barv 29 has formed at its upper edge a plurality of grooves ornotches 35. The locking pin 36, is a slidable lit in the aperture 41 of the bracket 37, `which is attached to the wall 12, as atr38. The locking pin 36, has a pointed lower extremity 39, which may be held in engagement with any desired one of the grooves 35 by the coil spring 40, which is located in the aperture 41, and superimposed between the upper extremity of the locking pin 36 and the bottom of the cap 42, which is threadedly attached to the bracket 37, as at`43, it being understood that theforce of the coil spring 40 may be increased or decreased by screwing the cap 42 downwards or upwards.`

The extremity 44 of the horizontal bar 29 is a slidable lit in the adjustable member 45, which, is provided with an aperture 46, at or near its outer extremity to accommodate a cord 47, chain, or iiexible member.

The extremity 44 of the horizontal bar 29.

is provided with a plurality of Vapertures 48, of equal'number and spaced the same distance apart as the heretobeiore mentioned grooves 35 in the bar 29, there being an aperture 49 located in the adjustable member 45, and registering with any desired one of the apertures 43 located in the extremity 44 of the horizontal bar 29, and held in engagement by means of the pin 50.

The cord 47 is extended over pulleys 51 attached to the wall l2, so as to permit the cord 47 to be attached to one extremity ot the bell crank 52, as at 53, which is pivotably attached under the floor 13, as at l, and has its other extremity 55, in contact with the movable portion 56 oi the floor 13, which is held normally in a flush posit-ion with the floor 13 by means of coil springs 57 conveniently located under the movable portion 5G ot the floor 13, the movable portion 5G having flanged edges o8 to engage grooves suitably located in the floor 13 to enable the coil springs 57 to hold the movable portion 56 in a flush position.

Y Referring in particular to the functioning or operating oit my improved device.`

lt vvvill be understood that the supplementary sate door may be raised above the safe door, as clearly described and heretobe'tore set forth. lt will be also understood that the supplementary sate door may be held in the above mentioned position by means of the pointed extremity ot the catch lever when engaged with the notch ot' the catch 22, at which time the pointed lower extremity of the locking pin is engaged with one of the grooves in the upper edge ot the catch lever.

lt ivill be further understood that when the movable portion of the floor is stepped on, that the cord Will be pulled which Will disengage the catch lever, and the supplementary door will tall covering the salie door.

It ivill also be further understood that the catch lever and the catch may be engaged in a vertical position, or at slight angular relative positions by means ot the plurality ot grooves located in the horizontal bar, which will render the operation ot my improved device more sensitive, as'may be required.

It will be further understood that the plurality of apertures located in the eX- tremity oi' the horizontal bar and the adjustable member will compensate for the heretobefore mentioned sensitiveness ot operation ot my improved device.

lt will also be 'further understood that when the supplementary suie door is dropped, that the loci-t 59, attached to the supplementary safe door will lock the supplementary sate door in a closed position, and will also complete the circuits 60 andGl, which will cause the batteries 62 and 63, or any convenient source of electric current, to ring the bells 64 and 65, gongs or signaling devices, respectively, which may `be located at the police station, protective asencys office, or at any suitable convenient place.

lVhile l have above described the preferred torni. construction and arrangement of the several elements employed, it will be understood that the device is, nevertheless` susceptible of considerable modification therein, and l therefore reserve the privilege ot resorting to all such changes as may be fairly embodied Within the spirit and scope of the invention as claimed.
